This is the only solution on the market that is directly compatible with Toyota brake lines without the need to cut, flare the lines, add adapter lines or fittings. Other valves on the market with metric ports are bubble flare, and do not fit Toyotas.

Additional Information:Who needs this part:

If you have a 9/75 - 7/80 U.S. spec Land Cruiser FJ40 with front disc / rear drum brakes, chances are you need this part. By now virtually all of the original units we've seen have severe internal corrosion. Many owners will not realize their brake performance is compromised until they encounter a hard stop situation.

If you have a pre-9/75 FJ40 with full drum brakes, and you are doing a disc brake conversion, then you need to add a proportioning valve to avoid rear brake lock-up.

If you own other types of Toyota with a similar proportioning valve configuration (one inlet port and one outlet port), you can use it to replace your leaking or corroded OEM part. In many applications, the OEM part is no longer available or very expensive.

If you are customizing a Toyota for racing, then you already know you need this part!
